1. Giun đũa và giun kim sống ở đâu?

  • Giun đũa: sống trong ruột non của người.
  • Giun kim: sống chủ yếu ở ruột già và hậu môn (đặc biệt vào ban đêm, giun cái bò ra hậu môn để đẻ trứng).

2. Loài nào gây nguy hiểm hơn? Vì sao?

  • Giun đũa gây nguy hiểm hơn vì:
    • Chúng có kích thước lớn (có thể dài tới 25–35 cm).
    • Khi nhiễm nhiều, giun đũa có thể gây tắc ruột, thiếu dinh dưỡng, chậm phát triển ở trẻ em.
    • Ấu trùng giun đũa có thể di chuyển qua phổi, gây ho, khó thở, viêm phổi.

=> Giun kim tuy gây ngứa hậu môn và ảnh hưởng giấc ngủ, nhưng ít gây biến chứng nguy hiểm như giun đũa.


3. Các biện pháp phòng chống giun sán ký sinh:

  • Ăn chín, uống sôi.
  • Rửa tay trước khi ăn và sau khi đi vệ sinh.
  • Không ăn rau sống chưa rửa kỹ.
  • Giữ vệ sinh môi trường, không phóng uế bừa bãi.
  • Tẩy giun định kỳ (3–6 tháng/lần).
  • Giữ móng tay sạch, cắt ngắn.

Tiếng anh:

Last year my mom surprised my brother and I with a train trip to the nation's capital - washington DC. We departed at night and woke up the next morning somewhere in Virginia. Looking at beautiful sight of the mountains while enjoying breakfast.

I had my 15th birthday while on this vacation and the crew said "Happy Birthday" to me every time they saw me.

My grandmother often shared stories of how she rode the rails back in the 60's as this was the most common way to travel back then. This trip gave me the opportunity to share my story with her as well. This trip brought my family closer. I will never forget it.

Bản dịch:

Năm ngoái, mẹ tôi ngạc nhiên khi anh trai tôi và tôi có một chuyến đi tàu đến thủ đô Washington DC. Chúng tôi khởi hành lúc ban đêm và thức dậy vào sáng hôm sau ở một nơi nào đó ở Virginia Nhìn cảnh đẹp của núi trong khi đang thưởng thức bữa sáng.

Tôi đã có kì sinh nhật lần thứ 15 vào đúng kỳ nghỉ này và Các hành khách trên tàu đã nói "Chúc mừng sinh nhật" với tôi mỗi khi họ nhìn thấy tôi.

Bà tôi thường chia sẻ câu chuyện của bà đi trên đường ray như thế nào trong vòng 60 năm vì đây là cách phổ biến nhất để đi du lịch hồi đó. Chuyến đi này đã cho tôi cơ hội để chia sẻ câu chuyện của tôi với bà. Chuyến đi này đã mang gia đình tôi gần gũi hơn. Tôi sẽ không bao giờ quên nó

bn tham khảo ạ

English is the most common language all over the world. There is no compulsory method to study English, but each person has to find the suitable one to study it efficiently. To me, I read books in English in order to improve both my vocabulary and grammar. Besides, I combine studying and entertaining. In my free time, I often listen to English songs, watch English movies and try to translate the lyrics as well as the subtitle. Furthermore, I join an English club, where I can connect with some international friends, and they are the best teachers to teach me about English. I can learn some slang, idioms, and things that normal teachers do not teach their students. I hope you can find your own ways to learn English.
